Brushless motor with integrated electronics BLDC 58 Description The BLDC 58 is a variable speed 24 Vdc brushless motor with integrated drive electronics providing up to 50 watts continuous output power and a variable speed proportional to a 0-5 V control signal. The unit provides a compact solution to a variety of light industrial applications such as conveyor drives, paper feed and pump drives. Scientific applications include stirring equipment, peristaltic pumps, mixing machines, as well as any variable speed application that requires long maintenance free life and operating speeds from 100 to 3000 rpm. The motors design incorporates an external rotor and magnet system which provides particularly smooth running, high grade bearings and drive electronics, all of which are housed in an enclosure suitable for use up to IP55 operating conditions. The inclusion of the drive electronics within the motor greatly simplifies the use of the motor as well as reducing overall system cost.

Simply connect a speed control potentiometer and direction switch for bi-directional velocity control. A digital output signal also enables motor speed to be accurately monitored. Version with brake When the control signal input level is < 0.5 V the internal electronics brake is activated to achieve a rapid stop The brake circuit is not active when the motor is in a stationary condition. However the de-energised detent torque is usually sufficient to retain the position of unbalanced loads when the motor drives through a gear reduction. When the control signal is > 0.5V but < 0.9V the motor is disabled, thereby creating a deadband for control purposes BLDC58 Typical connections for simple speed control MOTOR Lead colours 24 Vdc 8.2K 8.2K red black SPEED CONTROL INPUT 2.2K white n/c BLDC 58 Brushless motor green DIRECTION brown 2.2K Lead wire Shield connect to motor ground Mclennan Servo Supplies Ltd.
